Given the table, write and equation for the function, and describe what it does. ASAP!!!

k0ka [10]

Answer:

f(x) = 3x + 1

Step-by-step explanation:

f(x) = 3x + 1

f(1) = 3+1 = 4

f(2) = 3*2 + 1 = 7

f(3) = 3*3 + 1 = 10

f(4) = 3*4 + 1 = 13

it's a linear function with slope 3 and y intercept 1

5/2.35 = x/12 what does x=

postnew [5]

Answer:

$x = \frac{60}{2.35}$ or $x = 25.531...$

Step-by-step explanation:

Step 1: Cross Multiply

$\frac{5}{2.35} = \frac{x}{12}$

$5(12) = 2.35(x)$

$60 = 2.35x$

Step 2: Divide both sides by 2.35

$60 / 2.35 = 2.35x / 2.35$

$x = \frac{60}{2.35}$ or $x = 25.531...$

Answer: $x = \frac{60}{2.35}$ or $x = 25.531...$

The perimeter of a rectangle is 4040 yards. what are the dimensions of the rectangle with maximum area?

Ivanshal [37]

Let x be the length and y be the width2x + 2y = 40x + y = 20change that into y = mx + b formy= 20 – x
Area =xy = x (20-x) = 20x - x^2Area=-x^2+20xcomplete the square:Area=-(x^2 – 20x + 100) +100=-(x - 10)^2 + 100This is an calculation of a parabola that opens downward with vertex at (10,100), which means maximum area of 100 happens when x, the length=10)Dimensions of the rectangle with maximum area? 10 yds. by 10 yds., a square.

Find the coordinates of the y-intercept and x-intercepts of the following. (image!)

marissa [1.9K]

Answer:

Step-by-step explanation:

We can do this a couple of ways. We can graph it -- see below. Or we can do the math.

Math

y = x^2 - 2x - 15

This trinomial factors into

y = (x - 5)(x + 3)

from which

x - 5= 0

x = 5

and

x + 3 = 0

x = - 3

The y intercept is the value obtained when all the xs on the right = 0

y = 0^2 - 2*0 - 15

y = - 15

Answer

x intercepts: (-3,0),(5,0)
y intercept: (0,-15)

The graph is below.
